Jiamat

Jiamat is a recurring large green dragon; the last of his kind. He is able to speak with people and has been in the past willing to allow the chosen to ride on his back.

Magical Mutiny
Jiamat first appears as nothing more than glowing eyes to the Heroes of Time, roaring that they are nothing more than liars. The heroes escape to the Isle of the Ancients before he can break out of the cave.

The Trident Key
A much younger Jiamat is introduced to the heroes by Drew Seld during their trip to the past. He is very friendly to the group and offers to fly them to the Tropical Graveyard to hide the key.

However Jiamat is betrayed and trapped in the cave on purpose by Harry, thus explaining why Jiamat no longer cares for humans.

Fire at the Tombstones
Jiamat finally breaks free from the cave and begins to wreck havoc on the battlefield. The heroes are already struggling to take down Marlon Sinus. It is only with the intervention of Nekro Sander that the heroes escape, being catapulted three months into the future in the process.

Festival of the Shadow Winter
A passerby notes that Jiamat has been burning down most of Bergahorn over the last three months.

The Border War
Jiamat is seen flying over the town of Rand, which terrifies the defenders and causes the Acacisan Army to overrun the city.

Battle of Carcino Bay
Jiamat begins the Battle of Carcino Bay by burning down part of the Carcino Wall, allowing both Trident and the undead armies led by Raorg into the city. Although severely injured by Azrael, Jiamat kills thousands by unleashing acidic needles from his scales and then he flies off to recover from his wounds...

The Frozen Fort
The body of Jiamat is seen lifeless in front of the Frozen Fort later by the Heroes of Time. The body is the subject to a necromancy ritual which reanimates his course. Jiamat then attacks the party alongside Magnus Tenebris one last time before finally crumbling into dust, the dragons dying with him...
