The Adventurers' Guild — an Isekai RPG Leveling Add-on
The base mod talks about the Adventurers' Guild a lot. This add-on actually puts them on the map.
They send hunts to your quest board, raid you if you cross them, and at high reputation their legendary hero might show up at your gates with three of his friends and ask to stay for a few days.
The Guild

One faction, one unique settlement: a procedurally-built Guild Hall with a throne alcove on a carpet, a banquet aisle running between stone pillars, a barracks wing on one side, and an armory full of weapon racks and a forge on the other. Lit plaza out front.
Inside, 40 named members across every rank from F to SSS. The two that matter most:

- Arthur "Excalibur" the Hero, SSS rank — strongest of them, but not the leader. Always wields the Legendary monosword Excalibur +10.
- Magnus "the Sage" Pendrak, SS rank — Guild Master, the one actually in charge.
On top of these exceptionnal characters, the faction sub-lead council counts 5 more S rank adventurers.
The other 33 fill out the ranks: 6 A, 8 B, 8 C, 6 D, 3 E, 2 F.
Every guild member have a particular name that you guys might recognize, and wears the same grey uniform — plate armor with Royalty, flak vest without, plus a duster for A-rank and above. No helmets, no random clown apparel.
Quests


The Quest Board have its own custom UI. Click the gizmo on the Guild Hall to open it. Five rolling contracts every in-game day, scaled to your strongest pawn — hunts at low ranks, expeditions in the middle, raids on legendary monsters at the top.


Recruitment Duel unlocks at +25 goodwill. A Guild adventurer walks onto your map and picks a fight. Get them below 40% health or knock them out and they defect to your faction. Kill them outright and the Guild takes note.

Hero's Visit unlocks at +75. Arthur and three of his closest companions arrive at your colony as honored guests for three in-game days. Keep him content — decent food, a guest bed, no horror tunnels — and you walk away with silver, a Masterwork weapon, and a serious reputation jump.
Let his mood crater and he leaves in disgust. Let him die and the entire Guild goes permanently hostile, with the surviving three immediately turning into a raid on your colony.
Compatibility
Works with Vanilla, Royalty, Ideology, Biotech, and Anomaly. With Royalty loaded the Guild prefers plate armor over flak, which keeps things looking right in medieval scenarios. Existing saves work fine — the roster generates on first load.
Performance was a priority: tick loops are throttled, no LINQ in hot paths, no patches on stat workers or other hot vanilla methods.
Requirements
- Harmony
- Isekai RPG Leveling (MAIN MOD)

This add-on requires Isekai RPG Leveling, my main mod with the rank/leveling system that powers the whole Guild hierarchy.
A few practical things: the Guild Hall is built once at world creation, so you'll only see it on a fresh world. The quest board refreshes every 24 in-game hours, so grab the contract you want before the day rolls over.
