The Entity

From DALpedia

The Entity was a creature that was summoned from a dark dimension when Haraldur used the Legendary Weapons to open up a gate to the dimension so he could seek out his revenge, and complete himself.

The Entity appeared in the ruins of Duilin's house in Laus, were the gate was opened. He first appeared a frightening looking child and approached Duilin and Kami-Ryu. He then proceeded to rapidly age, to a young man and made several clones himself.

The clones were soon defeated, but the main entity survived and was combined with Haraldur. Haraldur then went berserk and began trashing the area, and killing everything in sight. This is known to be the main reason of the rivalry between Zeros' and Haraldur.
