Complete the tasks
Every game has some tasks for which you will receive Soul Gems.
Receive rewards
You can exchange your Soul Gems for Steam Wallet top-ups, game keys, CS:GO Skins and other rewards.
There should be a function which allows you to trade with others and sell your runes to them for soul gems. Anyone agree with me? Also, how do I make it so that the moderators of Gamehag see suggestions? Thank you.
