The true identity of Ostaros came as a complete surprise to me!

New theory about the meaning of the name "Ostaros": the word "ostaro" means "skeleton" in Esperanto. This may be a reference to Ostaros being the first of a new breed having been built from "bare bones." Or perhaps a reference to Ostaros being the underlying structure for Springer.

Anyway, I now know two words in Esperanto, the other being the word for 'yoghourt' (Yakult).
