The Realm Chain

The Realm Chain is the tether Morodin created that prevents Orukheim from being pulled into the Void. The chain is millions of miles in length and is made of pure adamantium, the strongest substance in all the Realms. Many brave Valorks have attempted to scale the chain, but none have ever reached Asgard. When Gruumsh lead the Valorks into Midgard, he severed the chain, sending Orukheim adrift into the Void.
