Ifferstone

“Basically, it's a shard of the Iffermoon that is crafted to make a simple statement. In this case: IF I were there. So as long as you have it with you, I can appear with you if you need me.”"— Dinandus."

Ifferstone is a shard from the Iffermoon that can bend reality. Most denizens of Dinostria seem to have an Ifferstone of their own. A person can give their Ifferstone to another and summon them when in need. In Iffermoon, Silence can collect up to 14 Ifferstones in which he summons party members in battle.
