A soul rune obtained in the Runespan is created by siphoning soul esswraiths, living souls (both requiring 90 Runecrafting) or undead souls (with 95 Runecrafting). Siphoning grants 106.5, 213 and 144/255.5 experience respectively.
If you try to bank any runes or essence from Runespan you get the message "A magical force prevents you from banking this item."
