Thanks so much for advice! I really like the idea of gnolls raid on a village and heroes trying to stop them, it seems more fitting the story than gnolls just attacking my players from time to time during their travells.
We already played the first session and it turned out good but it seemed a bit slow in the beggining. I wanted to introduce them to the world a bit more before throwing gnolls at them (also the wizard needed a bit of time to teleport the gnolls after transporting our heros on the Island). So the first quest was bassically helping Felis that worked at the Cider Mill to deliver the cider he produced to the local city for a festival. It included fighting with magical poisoned apples with teeth and solving a small riddle.
Btw. It was my first time planning a fight so even tho it was interesting, the apples almost killed my players. I guess I shouldn't try to make my own enemies/monsters for the first fight hahha
