Side Quests
The Weave weaves where the Weave will. Sometimes those who travel across it are taken up by it, moved in a direction they did not know they would move in, even against their wishes. And sometimes, those who travel across it possess such strong fates that they dance on the Weave, and it swirls and stretches around them, pulling adventure around them, and bending fate to their wills.
These Quests are meant to be played alongside the Great Weave story. If you are playing the Great Weave, you will only unlock this ability at a certain point in the story.
Side Quests allow players to play separate games apart from the primary storylines and give particular bonuses to the players that are willing to embark on the quests. I would encourage you to develop a particular narrative around why your character seems to be on these side quests. For example, your character may have heard of an ancient weapon nearby from some travellers, so they seek it out, or possibly your character is simply distracted, taken up by fate and put on a slightly different path than was expected. No matter the reason, make it your own and tie it into the greater narrative if possible.
