The Moon

Arbressian's moon is special in many ways but most notably because it is the home to two of the Creator Gods, Corellon and Sehanine. The moon is actually the Feywild, another plane of existence.
From the Prime Material plane the moon's surface looks like a mix of purples, blues, reds and pinks. There is a full moon for three days per month. The moon phases aren't based on the placement of it in relation to the Prime Material and the sun, instead it is because of its rotation. One side of the moon is always vibrant and emitting some light while the other side is always swathed in shadow and doesn't have strong enough light to show in the night sky, so the phases are depending on what stage of the rotation the moon is in.

Geography

The bright side of the moon is full of colourful landscapes such as lush forests, expansive fields, and mountain chains, all with colours not typical on any other plane of existence. Here the colours of grass and other plants come mainly in various hues of purples, pinks, reds and blues which is what gives the moon its colour as seen from the Prime Material plane. A lot of the plants are also bio-luminescent and glow brightly during nighttime.
On the other side of the moon, the landscapes have more subdued colours of blues and silvers and any light shining there seems to be dimmer than it should be. There are deep forests and lakes with beautiful crystal clear water. Meadows with delicate flowers and rolling hills and valleys. Everything looks a bit like it has been taken out of a romantic fairy tale and been made real.

Tourism

The Feywild is probably the most popular plane of existence to visit for those from the Prime Material plane with high enough skill in magic to make such a trip. Portals to the Feywild also open up in various places on the Prime Material frequently enough that quite a few people enter that way, sometimes by mistake. 
With Corellon and Sehanine being creators of elves, a great deal of travellers to the Feywild would naturally be elves who wish to see the home of their primary gods. It is also popular with firbolgs and other such races who were created in the Feywild after the world had split apart into different planes of existence.
