Household spirits work in the dark of the night and so do I. Let me present the Brownie in support of the GURPS Dungeon Fantasy RPG kickstarter.
Brownie (25 points)
Choice Professions: Innkeeper, Ninja, Thief, Wizard
Marginal Professions: Barbarian, Holy Warrior, Knight
These humble household spirits are often ridiculed by the more adventurous faeries like Pixies, Leprechauns and Fauns – the drab brown clothing doesn’t help either – but many an adventuring party has found them an unexpected boon. Given the chance Brownies would stay in their favourite household forever, but that’s hard to do if the tenants get torn apart by hordes of skeletons. Fortunately, they are quite adaptable. Traditionally acknowledged as masters of stealth, they are able to cook a five-course meal without waking anybody in the house. That their housekeeping skills are without par goes without saying, but only recently have adventurers woken up to the fact that this also applies to butchering monstrous foes…
Unusual among adventuring types, Brownies are not big on being paid. Many go so far as to regard payment as an insult. Fortunately even the most stiff-necked Brownies wouldn’t consider shares of loot to be payment and food given to them is always a gift, right? Brownies get along best with down-to-earth types, who enjoy good food and drink – like Barbarians and Dwarves. As domestic faeries nature comes a distant second to creature comforts, but they do feel some empathy towards animals and plants.
Brownies are strong for their size, but not quite as strong as Leprechauns. They are every bit as tough, though. Find height normally for their ST and multiply the result by 0.3. Weight is generally in the 5 to 10 kg range, but extremely fat Brownies coming in at 20 kg most certainly exist.

*The full skill bonus applies to manual work involving tools and up to full arm movements. Yes, this includes drawing weapons and aiming, but not actual fighting.
**Household Spirit: Your knowledge of household tasks is truly supernatural. You can literally turn monster entrails into gourmet food. This Talent aids Animal Handling: (for domestic animal types only), Cooking, Leatherworking, Professional Skill (Dungeon Butcher)† and Pharmacy (Herbal). Only Brownies may have it and buy up to two more levels at character creation. Reaction bonus: Innkeepers and ordinary, hard-working folk (a small group by Dungeon Fantasy encounter standards). 5 points/level.
