Three different organizations (or, perhaps, two organizations and an individual) have united under one common cause: Drive the Far Realm out of the So-Lar System.

Those groups are:
-The Militant division of the Church of Celestian: the Hand of Celestian. Paladins and priests that keep Space safe for travel.
-So-Lar, the Reigar that has adopted the system as his personal protectorate, and is either names after it, or is it's namesake.
-Odd dragonborn from Earth, of all places. neither Chromatic nor metallic, but with scales more like crystal formations in most of the usual colors, plus the odd purple.

The Church will provide a Letter of Marque from Barney's Heir, and such aid as might be necessary for healing (and room and board) between missions.

So-Lar will provide (in theory) one of his six Warlocks.

The Dragonborn will provide a ship and supplies as they need appropriate. And maybe a crewman or two.

The players will provide cannon fodder for the war against the Far Realm.

This is likely to be a combat heavy game. And not all ship to ship. Boarding and melee fighting is to be expected.
