Islendigar is a French-language fantasy role-playing game set on Ter, a fictitious Ice Age continent inhabited by six tribes, inspired by the peoples who once inhabited the north of the world (like, Vikings, Celts, Inuit, etc.). The player characters are exceptional individuals among these tribes, imbued with the powers of a totemic animal-spirit.
The character generation uses a variety of steps, including a multiple answer test, free choice of traits, and distribution of characteristics points. The task resolution uses a pool of d10s, depending on the characteristics and competences: the dice results are summed, and the total is compared to a difficulty level. In combat, the margin of success is used to determine the damage. The magic system is based on spells related to the five elements (air, water, fire, ice and earth).
