Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Special Summon 1 "Dragon Ruler" monster from your hand, GY, or banishment, then immediately after this effect resolves, you can Xyz Summon 1 "Dragon Ruler" Xyz Monster using only "Dragon Ruler" monsters you control. During your Main Phase: You can banish this card from your GY, then target any number of your banished "Dragon Ruler" monsters with different Attributes; return them to the GY. You can only use 1 "Here There Be Dragons" effect per turn, and only once that turn.
