Muldrasil

Last updated 2026-05-01

Muldrasil was a living artificial tree-shaped world where the Wingweavers and Cnidaria organisms previously resided.[1][2] It was previously damaged by the Reignbow Arbiter during the Flaming Catastrophe, and fully destroyed by the Antimatter Legion around 5320 Star Calendar.[3][4]

The surviving Wingweavers have since been reduced to mercenaries and intergalactic pirates,[1] although the Xianzhou Yuque suspects that the Wingweavers' Peacock Legion may be trying to revive Muldrasil.[4]

History

Muldrasil was the home of the winged subspecies of primate hominids known as wingweavers. It was a living artificial tree-like world with branches that allowed the wingweavers to warp to other worlds and plunder them for resources.[1][5] It drew energy from the stars, and has been described as a star devouring "Dyson tree."[3][6]

In Year 3400, Muldrasil began approaching the Xianzhou Luofu, as if attracted by the power of the Ambrosial Arbor onboard. In the event known as the "Flaming Catastrophe War", a battle broke out between the Luofu and Muldrasil. The Reignbow shot an arrow into the Ambrosial Arbor, severing its connection with Muldrasil and ripping open a fissure into the void, releasing a monstrous wave of imaginary force. This resulted in the destruction of Muldrasil.[3][6]

Muldrasil was completely destroyed by the Antimatter Legion around Year 5320 Star Calendar. The wingweavers became lost wanderers in space, reduced to mercenaries and intergalactic pirates.[1]

A Yuque intelligence report notes that based on IPC data, the wingweavers' Peacock Angel legion have arrived at the Consternation Starzone to locate a Stellaron and revive Muldrasil. The information has yet to be verified.[4] According to the speculations of the Yuque's Divination Commission, there might be more than one world like Muldrasil.[1]

Structure

The wingweavers allotted their positions in Muldrasil strictly according to their social structure. At the topmost branch was the Wingperor, who was traditionally considered an Emanator of Abundance. Under that branch lived the Sky-Defenders, Hymn-Singers, Infant-Nurterers, and Bough-Pickers. Below all these branches were the Residents of Dirt. As Muldrasil is now destroyed, the social structure of the wingweavers is no longer clear.[1]
