Soon Lith started to hear the clangor of a furious fight, indicating that he was getting close to the front lines of Demons. A few doors leading to the private quarters of the undead's upper echelons were still closed, their enchantments strong enough to keep the black tide at bay.
Yet.
The Demons had no time or wish for finesse so they just took deep breaths and hurled streams of Origin Flames in unison. The resulting Thousand Flames burned at the defensive arrays, forcing their runes to shine bright as they drained their energy source to resist the onslaught.
Alas, there was no mana geyser below the Derios branch so the only way to fuel permanent arrays was to use mana crystals. No one had the luxury of the time to replace the crystals once they ran out of world energy so there could be only two endings.
