Galhaf is the fourth planet orbiting Chihazh, home to two sapient species, humans and pteranthropans, and a rich diversity of other life forms. The name is derived from the Classical Kasshian wagallapa, from wagalla "world" and -pa "our". Wagalla in turn was derived from the verb gli "to make, to create", and originally meant "creation". The Nrastaists believed that there were many worlds, different creations of Goddess via various groups of Divinities. The word for "creation" came to be used for these worlds, and thus, their own world was referred to as simply "our world". Galh on its own still means "world" in Ivetsian, although the meaning of the -af has been lost

Physical structure

Overall, Galhaf is similar to Earth. It is slightly less massive with a similar composition, resulting in a slightly weaker surface gravity. Its rotation is slower than Earth's, resulting in a day somewhat longer than our own. Like Earth, Galhaf's surface is divided into several tectonic plates, and thus, phenomena such as earthquakes and volcanoes occur in much the same way as on Earth.

Geology

The planet's landmasses are more spread-out than Earth, broken up into a dozen or so mini-continents and two major continents.

Major continents are:

Atmosphere and climate

Galhaf's atmosphere is similar to Earth's, but is slightly thicker with a stronger greenhouse effect. Galhaf's surface temperature averages a little higher than Earth's.

Seasons

Galhaf's axial tilt is slightly larger than Earth's, resulting in greater seasonal variation due to axial tilt. The seasonal variation is complicated by the moderate degree of eccentricity
