Legend Lore: Seal of Ordovich'airth

The Seal of Ordovich’airth is one of 5 {LuQnJpFdRwN'SxL} Seals; powerful Sequesters designed to seal away Great Wyrms and to siphon their Wyrm Strength. It is theorized that if a Dragon were to live beyond its natural life cycle, it could evolve into a Wyrm, and beyond that - A Great Wyrm. It is believed that only a Wyrm is capable of killing another Wyrm. If one is able to slay a Wyrm, then by Dragon Logic, they too are wyrmkind.
And so, only Wyrm Magic can seal away a Wyrm; the Seal of Ordovich’airth was designed to be a prison for Ordovich’airth. In life, he was a cruel and vicious Dragon that enjoyed consuming his victims’ souls - preventing them from reaching the afterlife. So in return, the Seal of Ordovich’airth was then hidden away in a pocket dimension, haunted by the souls of those he tore from life and death.
Ordovich’airth likened himself as a God of Annihilation - and so the only way to break the Sequester is for the Seal itself to be Annihilated with equal strength. But this too becomes a double edged sword - as the Seal of Ordovich'airth is the only way to break {LuQnJpFdRwN'SxL} Seals.
