Astronomical evidence
Kepler-90 contains eight catalogued transiting planets. Its outer giant Kepler-90 h is listed as KOI-351 h in this project's saved NASA catalog, so the assignment uses that exact identifier. [1,2] The image invents a moon from which the parent giant crosses the host star. An occultation can hide a stellar photosphere; the depicted small bead at the planetary limb represents emergence. Neither this moon nor this event has been observed.
The illustrated viewpoint
Tawny humanoid with flat cranial plates in a cross-legged seat with arms forming an overhead oval. Terraced limestone basin with shallow mineral channels. The satellite, orbit, limestone terraces, pools, atmosphere and warrior are invented. The giant's angular diameter, occultation timing, illuminated rim and exposure are not calculated from a dynamical model. The small star emerging at the limb is an artistic configuration; this is not a forecast of an eclipse.

Peace and strength are visual themes; no character thoughts, teachings or biological cosmic-energy mechanism are supplied.
