The black shadow of a raven flat on sleeping Koc'h. A raucous crussage takes the korrigan out of his torpor. Siobhan! Siobhan has disappeared! His tracks led Koc'h to Wales, a land of the Tylwyth Teg, the Red Dragon, and Taliesin, the greatest bastard of all time. And of the bards, it is precisely mentioned, since Koc'h goes to the Eisteddfod, the assembly of Celtic storytellers. Not to shine there by his stories? Oh no! To put all his art at the service of his revenge.
