Lounge

A place to rest in a ship. From Silverlake you can buy healing crystals, fireplaces, and firewood racks that can be placed in lounge to assist in your recovery from exertion. A fully stocked lounge isn't quite as good as a player city crystal combined with a ranger's campfire, but they are still pretty effective.

Crystal sphere

Enchanted spheres can be added to lounges to help with your spellpoint and to a lesser extent, endurance point regain. They need no fuel, and give better spell points than a player city crystal, but less endurance points. From silverlake for ~40k gold.

Fireplace

Lounges can be equipped with fireplaces to speed the recovery of hit points and to a lesser extent endurance points for all those in the room. Many wooden items can be dumped in to instantly catch fire. The strength and duration of the fire depends on how much wood has been added to it, but even just a handful of torches will last a decent while. From silverlake for ~40k gold.

Firewood rack

Firewood racks offer a long term storage solution for firewood. To restock it, place <wooden item> in rack butn ote that they need to be heavier than 1kg. Just stoke to add more wood to fireplace. From silverlake for ~15k gold.
