The slight spelling change of Alma Toran has been done for the following reason:

It is possible that アルマ・トラン comes from Arabic 3ālam Ṭurran (عالِم طُرّاً), which roughly translates to "The World in its entirety". Therefore, I suggested that a second "r" should be added to "Toran". So: Alma Torran.

FUTHERMORE: Rather than 3ālam, it is also possible that アルマ comes from the Arabic word أرومة‎ Arūma(t), meaning "source/origin/root/beginning/etc". However, since the nature of  アルマ・トラン is still unknown, it isn't clear which is better. If future details points towards  Arūma(t) being the more appropriate source, then the spelling of アルマ・トラン will be changed again to Aruma Torran. But as I said, there isn't enough evidence to warrent that change yet.

What seems clear now is that トラン comes from Arabic Ṭurran (طُرّاً).
