Diactum says to Gregian:
Well dear sir, could you equip me with a tattoo displaying on owl, sitting on the branch of an ancient oak tree? Hopefully this allows me to improve my wisdom and knowledge of ancient events.
After Gregian has left the premises, Diactum adresses to all:
I think I have learnt about this mage guild... Back in my home-village, I once met a very old travelling sage who told me that some ground-breaking research was once carried out by a mage guild in Amstrad. A pack of wizards in this guild were investigating the possibilities to extend their life duration so that they could possess more time to experiment with magic. However, I don't know if they succeeded or not and I don't know if there were any complications. As we were told by Gregian, no one ever returns there...
So I happen to know the location of this guild, but only from what I was told. I think it is located three days travelling to the south-east, though we have to search a bit more when we arrive in those regions.
Shall we depart when we have had our second meeting with Gregian tomorrow?
