'''Tumi''' is a [[mistspren]] on [[Roshar]], bonded to [[Rlain]]. He's one of the true spren that have been Enlightened and transformed by [[Sja-anat]].{{book ref|sa4|114}}

Very little is known about Tumi's appearance. During the occupation of [[Urithiru]], he hid in the [[gemheart]] of a [[cremling]], remaining invisible.{{book ref|sa4|114}} If he's similar in appearance to the other Enlightened [[mistspren]], [[Glys]], he likely appears as a red crystal dripping light upwards in the [[Physical Realm]].{{book ref|sa3|115}} To [[Sja-anat]]'s sight, he looks like a glowing, shimmering light, constantly changing shape.{{book ref|sa4|i|2}}

He's not hostile to [[singer]]s the way other [[spren]] are, and considers it an honor to bond Rlain, even thinking him awe-inspiring. He's interested in exploring new things, even when they're potentially dangerous: he willingly underwent Sja-anat's transformation and expressed strong interest in the [[Rhythm]] of War, wanting to share the news of it with the rest of his siblings.{{book ref|sa4|114}} He reveres Sja-anat as his mother, and is grateful to her for the opportunity to see the world from a different perspective. He's also supportive of Rlain and hopeful about their bond, convinced that it will be something wonderful. He remains comforting to everyone he knows, regardless of their relative power. However, he is also cautious; he hides while in Urithiru, and follows Rlain for a while before introducing himself.{{book ref|sa4|111}}{{book ref|sa4|114}}{{book ref|sa4|i|2}}

Tumi can hide from sight of others by entering gemhearts of cremlings; he seems to have some control over the creatures this way, guiding them on a specific path. This allows him to stay hidden from [[Voidspren]] and [[Fused]] alike, even those designed to detect [[Radiant]] activity.{{book ref|sa4|114}} At times, his speech pattern is somewhat similar to that of the [[inkspren]], using phrases like "salvation will be".{{book ref|sa4|111}}

Tumi is a [[mistspren]], and as such grants Rlain the abilities of the [[Order of Truthwatchers]]. However, he was corrupted by [[Sja-anat]], changing the properties of the bond.{{book ref|sa4|114}} While he should still grant Rlain the [[Surge]] of [[Progression]], letting him heal others and grow plants, it's likely Rlain's [[Illumination]] will not function as it would for ordinary Truthwatchers.{{book ref|sa4|6}} Most notably, he grants Rlain the ability to see visions of the future, and seems able to induce them, or at least encourage them to appear. Like with Glys, the visions take form of images made out of what looks like stained glass.{{book ref|sa4|111}}

|Tumi to [[Sja-anat]]{{book ref|sa4|i|2}}

While the circumstances around Tumi's transformation are unknown, it seems he deliberately approached [[Sja-anat]] to be Enlightened.{{book ref|sa4|114}} When that happened is unknown; however, a year into the [[True Desolation]], [[Sja-anat]] sent him to [[Urithiru]] to investigate members of the [[Ghostbloods]] for a possible bond, due to [[Mraize]]'s efforts -- through [[Shallan]] -- to get the [[Unmade]] to cooperate with him.{{book ref|sa4|13}} While Sja-anat was hesitant to let Tumi go, wary of both Mraize and [[Odium]], Tumi insisted on forming a bond and set out.{{book ref|sa4|i|2}}

At roughly the same time, [[Renarin Kholin]], the only other Truthwatcher to have bonded an Enlightened spren, convinced his father to allow "corrupted" [[Surgebinder]]s into the ranks of [[Knights Radiant]]. When Glys asked who else would join their ranks, Renarin almost immediately suggested [[Rlain]], the only [[singer]] within [[Bridge Four]].{{book ref|sa4|54}}{{book ref|sa4|114}} Somehow, Glys managed to pass this request on to Sja-anat, who in turn sent it onwards to Tumi. As such, the mistspren started looking into Rlain, examining him as a potential bondmate.{{book ref|sa4|111}}

Before Tumi could form a bond, the [[Fused]] and their forces invaded [[Urithiru]], the Knights Radiant were rendered unconscious, and Rlain was locked up for being an essai, or "human-lover".{{book ref|sa4|60}} To hide from secretspren, Tumi entered the [[gemheart]] of one of the cremlings inhabiting the tower, and began following Rlain.{{book ref|sa4|114}} At some point, Rlain noticed it, and grew paranoid about the cremling's presence, suspecting that it was a [[Voidspren]] trying to spy on him.{{book ref|sa4|79}}

When the revolt against the Fused began in the tower, Tumi started following the group closer by, directing his cremling to go after Rlain as the singer led his group, including humans, [[Venli]]'s singers and Fused, to escape Urithiru. Impressed by Rlain's actions in bringing the three groups together, Tumi chose to bond him, and informed [[Timbre]], Venli's spren, about it. When Rlain asked Venli if she'd be willing to lend him one of the [[Reacher]]s following her, she passed on the news: Rlain had already been claimed by another spren.{{book ref|sa4|111}}

It was then that Tumi chose to reveal himself. Showing Rlain a vision of [[Kaladin]] swearing the Fourth Ideal and [[Urithiru]] coming alight, he bestowed the title of Bridger of Minds onto him and implored him to speak the [[Immortal Words]] and form a bond.{{book ref|sa4|114}} Rlain did so, becoming a Truthwatcher; from then on out, the two could communicate mentally, without speaking out loud.{{book ref|sa4|114}}

Over the course of the following day, Tumi learned about Rhythm of War, combining [[Honor]]'s and Odium's Rhythms similarly to how Tumi himself combined Honor and Odium's [[Investiture]], and grew interested in sharing news of it with his siblings. He also explained to Rlain that he approached him for a bond at Renarin's suggestion, though it was Rlain's own actions that convinced him it was worthwhile.{{book ref|sa4|114}}
