I am Koráki Havran. When I am summoned by humans, I must give them any favor they ask of me. However, they must wait 24 hours after they complete my ritual. If they do not keep a sentimental item with them for that 24 hour period, I will come back, and ask a favor of them instead. If they finish my favor, then I shall grant them theirs. I can be a bit grumpy at times, but mostly due to loneliness.
