The rest is provided by a few notable works in the collection of the inveterate Elven bibliophile, Yrsa. Many of which, I have been fortunate enough to peruse (you still owe an Answer, Yrsa, or all your hard work is forfeit!).

According to the Centaurs, after eight weeks of fasting, a great elder and powerful shaman‘s frozen corpse was discovered near the snow-capped peak of the highest mountain in The South. After communing with his spirit, the remaining elders broke from tradition and buried the body at the edge of Irongate Forest. In the body’s clenched fist, was Lysaeda.
