The former's pose is taken from the panel depicting The White Dragonka fully manifested from its stone slab, albeit with some notable differences, such as its pose being mirrored (horizontally) and slightly rotated, the addition of its "Reign of Destruction" attack, and the positioning of its claws and wings.
The latter's pose is taken from the panel depicting Mahado (as his ka) launching his attack at Blue-Eyes White Dragon's stone slab, albeit rotated upright.
This card's name is likely a reference to Yu-Gi-Oh! Duel 257 (Duelist Duel 198): "Memories of Fate", when Dark Yugi and Seto Kaiba witness a memory of their battle more than 3000 years ago.
