Yaroslav, the Wise

Yaroslav, the Wise, was a Sage, one of the Hatholrim. He was teached by the Great Sage, Peter, that teached him basically everything he knows. He lived in a high tower, in the north of the forest, away from the rest of his people. His tower hosted a big library, bigger than any other east of the Red Mountains. The books were of different origins, lore of the Red Dwarves, aswell as their knowledge, books coming from the South and some even coming from the West, past the Sea of Rhûn. Besides this, Yaroslav was a wealthy men, belonging to a noble family, even being it's last member, as the rest of his family was brutally murdered by the czar. He has a pupil, Ivan, a poor boy that he found while walking on the streets of the capital, asking for money. Yaroslav is currently 45 years old, and wants to teach everything that was teached to him to Ivan, before he dies.
