The smell of gunpowder blankets this tropical paradise.
Summer Isle is a populated island in The Aratel Sea, it is the Summer Company's headquarters and is the only location with access to firearms and Hunter's Braces for sale.
One of the most eventful populated islands in the Eastern Luminant, having basically the essentials of starter islands: an inn, guards, training gear along with nice additions, those being ores, more sources of food and NPC events you wouldn't find at Etris, Isle Of Vigils or Greathive Aratel. A good place to quickly resupply your rations and repair/gather equipment, and enjoy the tropical scenery.
The Summer Isle's main attractions are the firearms, which can be found inside the main building at the gunsmith, the prices being:
Flintlocks - 100 Notes. The first guns the player to access early-game, dealing 10 damage on hit.
Req: 20 LHT.
Revolvers - 200 Notes. Similar to the flintlocks with a slight increase in damage (13) and a massive increase in swing speed. (M1's flow into each other, spammable)
Req: 65 LHT.
Dragoons - 500 Notes. Similar to the flintlocks with a massive increase in damage (20), but cooldown increased. (M1 spam combo cannot be used)
Req: 65 LHT.
Notes:
Bullets can be purchased for five notes each, or they by crafted anywhere with one iron, creating 20 bullets per iron.
Firearms also come with an off-hand variant allowing you to dual wield firearms, or use a different weapon with one.
Firearms can be parried, blocked, and dodged like all normal attacks.
Funke, Thundercall Trainer[]
On the second floor of the Summer Company's castle, the Thundercall trainer Funke can be found.
To unlock Thundercall, the player must bring 2 Spark Glands to the trainer to be crushed into a vial, obtaining a Sparkblood potion.
You can upgrade your Thundercall mantras for 100 notes each, the price increasing by 100 notes with each upgrade on the specific mantra.
Summer Isle's cauldron is located in the same room as Funke.
Blacksmith[]
Within the tower on the right side of the castle's entrance stairs.
Works like any other blacksmith, won't communicate with you if you have negative rep.
Antiquarian[]
Within the castle's ground floor, situated in the same room as the Gunsmith.
Works like any other antiquarian, won't communicate with you if you have negative rep.
Modifier Trader[]
Within the castle's ground floor, on the opposite side of where the Antiquarian/Gunsmith are.
You can talk to them even as an enemy of Summer Company.
Scope [QUEST][]
Within the tower on the left side of the castle's entrance stairs, Scope needs to recover crates filled with explosives that have been stolen by the bandits/Ignition Union, and what other better way to retrieve the crates is there than just sending you to do it.
These boxes of explosives can be found all across Isle, usually being tended to by Summer Company guards post offscreen battle. Returning to Scope with one of these boxes in hand, will net you a chest that will have loot from the item table below, and a small amount of positive reputation with the Summer Company.
Scope could be a pun based on sniper rifles and other guns that have a "scope".
Shipwright[]
The Shipwright is located on the rocky beach within a castle like structure.
Works like any other shipwright, won't communicate with you if you have negative rep.
Inn[]
The Innkeeper[]
Allows you to set your spawnpoint at Summer Isle for 5 notes.
Won't communicate with you if you have negative reputation AND you will be kicked out if you set your spawnpoint at this inn and then get negative reputation.
Kujae[]
Can be found outside the Inn
Will give you something random out of his sack for 350 notes.
The sack can contain random equipment.
It's a scam.
The Guildmaster[]
Allows you to make a guild/leave an existing one.
Trig [QUEST][]
Trig is an NPC at the entrance of the Guildhall/Inn (if you have interest points on, it's marked as Guildhall). His quest sends you to find Asius, a merchant who hasn't been paying his dues to the Summer Company.
Asius can be found behind the Inn if you follow the path leading away from the Inn, in an alcove facing the hive.
You will be given two quest dialogue options after answering why you're meeting him:
I'll see what I can do.
No you bottom-feeder, hand over the money now or you'll be sinking to the 3rd layer.
[ End Dialogue ]
Answering with the first dialogue option and returning to Trig will cause him to send three Summer Company guards after you, and will get you negative Summer Company reputation, and zero EXP if you don't kill the guards.
Answering the second dialogue option will have Asius reluctantly hand you an invisible stack of ship documents, his vessel sunken at sea and the documents the final few things to show for it. Returning to Trig will have him reward you with not only positive Summer Company reputation and EXP, but will also unlock a rare Talent called "Armor Piercing" that can be obtained from Talent hands. (obviously, it affects only guns)
Trig could be a pun about the word "trigger" based on the Summer Company's association with ballistics.
Crime Tax Collector[]
Nepo, an NPC found on a bridge can reset your reputation with Summer Company. (You might want to memorize this, as it’s very easy to anger the Summer Company)
This place contains Jarvis, a NPC who allows you smelt two equipments into one, and an Arena.
Cave[]
A cave opening facing the Shipwright's building, easy to spot.
Contains Coal, Rock and Iron, enough for bullets and flint.
Within the cave is presumably a hive teleporter prototype, out of function
Circular Structure[]
A circular building located outside of the castle, near the blacksmith's place on the other side of the river
Within the structure is presumably a hive teleporter prototype, out of function.
In the circular structure, there are some glyphs. These glyphs are interactable by Blindseers , hinting towards how to progress and unlock Blindseer mantras.
Castle Ruins[]
A castle like building in ruins, nothing of interest is inside or near it, until you look closely. Inside the ruins, on the left or right side of the inside, you may find a small crack in the floor which you may drop down into. Inside, a basement could be found with barrels, and possibly chests.
You can get there by taking the zipline on the main castle, and continuing forward.
Additionally, the basement is the location of an NPC you need to talk to when in the process of obtaining the ChainwardenOath, which was added on the 26th of July, 2024.
The Summer Company cannon
The Cannon[]
An enormous cannon lying on the cliffs on the Summer Isle. If a player has negative reputation, the Summer Company will aim the cannon at them, and fire. It fires a hit-scan projectile, that launches players far away, deals a large amount of damage. A horn will play before firing, alerting the player to their imminent demise. The cannon will NOT fire if the player is swimming. If the player is sailing or on the island in front of summer isle, it will fire.
The cannon also serves as a fast travel point to the Songseeker Wilds. Provide 3 Spider Eggs to The Guy in the cave across from Meteor Isle at Hive, and then climb up onto the cannon. Just touching the barrel places you inside, and shoots you over to the Songseeker WIlds.
Located on an island behind the Inn. You have to get into this location by destroying the different colored wall (tested with shoulder bash) or using a teleport move.
Inside, there is a room decorated with trees, bushes and a blue fountain in the middle. Interacting with the fountain tells you that you need something to water it, but if you have a canteen in your inventory with water in it (the fountain sometime bugs out and you will need to rejoin to use it), The fountain will sprouts 6 random lotuses in the room and you can collect them. The fountain has a cooldown.
Events that spawn in Summer Isle. For more info, see Random Encounters.
Explosive Crate [QUEST][]
Summer Company Thugs with dead Ignition Union Footsoldiers, surrounding a crate with explosives, which you can turn in to Scope for a chance at good loot.
Explosive Crate Event
From what I have seen, if you also kill the Summer Company Thugs surrounding the crate, a chest will spawn.
Bandit Ambush[]
Bandits spawning on the front entrance's stairs in a group of seven, ambushing the castle's entrance.
You will be rewarded with a decent amount of XP upon killing all the seven bandits.
Bandits V.S. Summer Company[]
Bandit Captains and Bandits fighting with Summer Company Thugs.
You will be rewarded with a small amount of XP and a chest if you help the Summer Company Thugs win.
Ignition Union V.S. Summer Company[]
Ignition Union Footsoldiers fighting with Summer Company Thugs.
You will be rewarded with a decent amount of XP and a chest, which side wins doesn't matter.
Ministry Massacre[]
A Ministry Scout sitting at a campfire with several Bandit corpses around them.
You will be rewarded with a decent amount of XP and a chest upon killing the Ministry Scout.
Nepo's name may be a pun on Nepotism, which is gaining preference in society through relatives or friends, and is also referenced in a Talent card related to Reputation.
The only place to buy guns in Eastern Luminant.
When a player with bad reputation comes near Summer Isle, the big cannon will activate, giving a warning sound. Then, the cannon will shoot after 3–5 seconds.
The location may be a reference to the historic Somers Isles Company and Somers Isles which is now more commonly known as Bermuda.
