Do we know for certain that Kyabetsu was Delta Gorno I? The specific planet is not mentioned in any game texts, nor nay of the manuals, although we do have some facts in evidence:
- There is only one planet in Delta Gorno's "green zone"
- The Melnorme state that the detonation of their sun "cooked the life off the Shofixti homeworld", inferring that the planetary mass was not destroyed in the explosion
The above could lead one to assume that Delta Gorno I is indeed the planet, but the Shofixti are furry, which implies that they're adapted to cold weather, which means they might have been brought up outside the "green zone" in Delta Gorno.
