[volume & issue needed] Roma gave Captain Britain great physical strength and a quarterstaff that could be used for direct attack or emit a protective force field.

[7] Roma appeared in human form while reaching out to a recovering and disillusioned Colossus shortly after "Mutant Massacre" and before "Inferno."

[8] During this encounter, Roma was really being held captive in her Starlight Citadel by the Trickster (aka the Adversary), a deity who planned on destroying the earth to remake it into whatever image he chose.

Using Forge's spell, it took harnessing the souls of all eight active X-Men and Madelyne Pryor, who was there at the time, to create and shut the portal.

X-Men who have traveled through the Siege Perilous include Rogue (accidentally sucked into it while battling the Master Mold/Nimrod[12]), Havok, Psylocke, Dazzler, and Colossus.

[volume & issue needed] Roma had foreseen that Excalibur would become essential to the safety of the Omniverse; only a group with their specific talents could stop an unknown threat.

[volume & issue needed] Excalibur encountered the threat shortly afterwards: Necrom, Merlyn's teacher had been planning for millennia to use the Phoenix Force to increase his own power.

[17] Roma briefly appeared in Fantastic Four, when she sent Gatecrasher to kidnap Franklin Richards, thinking he was too powerful to stay on Earth and with his family.

[19] Mad Jim Jaspers and Fury return to attack the Starlight Citadel in a plan orchestrated by Roma's father Merlyn.

She is seen along with Saturnyne expressing their concerns about the Incursions that are destroying many dimensions when they are interrupted by Spider-UK who reveals that all the spiders across the multiverse are being hunted and killed.

Saturnyne rebuffs him rude and coldly, but Roma sympathizes with him and gives him a talisman that allows him to travel through the web of life in order to save all the remaining spiders.

[21] Following the rebirth of all existence after the Incursion crisis, Roma lost her position as the Omniversal Majestrix and ruler of Otherworld to Saturnyne and split apart from her father, Merlyn.

[25] She created the Floating Kingdom of Roma Regina, which become one of the provinces of the Fair Courts in Otherworld, but due to her desire for freedom and lawlessness, her queendom has become a chaotic (but gentle) hedonism ranging from candylands, ruckus dance halls, neon playrooms, and lusty pleasure zones.

[27] When her father unites most of the nations together in a invasion of the Starlight Citadel that forces Saturnyne and her allies into hiding, The Floating Kingdom of Roma Regina becomes one of the only parts of Otherworld not under his control,[28] it becomes a refuge for mutants who are being hunted down by Furies.

Roma brings together 10 specific mutants to help stop her father, declaring them the "Knights of X" and sends them on a mission to find the Siege Perilous.
