Ruins of the Tomb of the Primeval Kings

The Ruins of the Tomb of the Primeval Kings is a set of four explorable areas that offers challenging monsters and special unique items called the Hall of Heroes unique items. The Ruins are often referred to as the new Underworld in reference to the name of the first of the four maps, the fact that the "old Underworld" was closed off when the Ruins was first introduced, as well as creatures from the Underworld that plague the levels of the Ruins.

Getting There
Through the dark portal in the Tomb of the Primeval Kings.

Levels
The Ruins are divided into the following levels:
 * 1) The Underworld: Not to be confused with The Underworld explorable area, this is a much smaller map identical to the Underworld PvP map. All players need to do is wipe out the several groups of monsters in the area to advance to the next level. After clearing each level, a timer will start, showing the remaining time before the party will be transferred.
 * 2) Scarred Earth: This is a much greater map that is also identical to the Scarred Earth PvP map. It features three areas (where each team started in PvP) and a central area. Players start in one of the three and have to clear the entire area. This map has the very dangerous burrowed Chaos Wurms that can surprise a party and chase it for a long distance.
 * 3) The Courtyard: This is a large map identical to the Courtyard PvP map. Players face the siege Chaos Wurms in this area and again must clear all foes to advance.
 * 4) The Hall of Heroes: This is a vast map identical to the Hall of Heroes PvP map. Players must first clear their area, then make their way across the bridge and into the central hall where three powerful mesmer bosses, called The Darknesses, await. Upon slaying these bosses each one will drop 1-3 of the new Hall of Heroes unique items.

Creatures
This challenge offers monsters from the classical Underworld (the Terrorweb Dryders, Banished Dream Riders and Chained Souls), as well as new monsters: Grasp of Insanity, Scythe of Chaos, Chaos Wurms and the Darknesses.

All of the new monsters posses a devastating skill called Fingers of Chaos which seems to be aimed at preventing 1-2 team farming of this area.

The Ruins vs The Underworld
The ruins share similarities with the Underworld as well as some differences:

Similarities:
 * Terrorweb Dryders and Banished Dream Riders may drop Glob of Ectoplasm on occassion as they did in The Underworld. This provides an easier way for parties to farm for these very rare crafting materials. Although in the classic Underworld, 2-man teams were far more efficient at farming for Ectos.
 * The chests in the Ruins are also Phantom chests and require Phantom keys.
 * The design of the first two levels uses the same elements as the design of the Labyrinth in the Underworld.

Differences:
 * Entrance to the Ruins does not require that the party's territory has the Favor of the Gods. Entrance to the Underworld requires it.
 * Entrance to the Ruins does not require an entry fee of 1000 gold. Entrance to the Underworld requires paying 1000 to the avatar of Grenth.
 * There are no quests in the Ruins.
 * There are no unique item drops in the Underworld.
 * There are no reapers in the ruins.
 * You must kill everything in ruins.
 * Ruins is not as large as Underworld is.
