Inspired by Ringgar, I decided to make a pretty detailed character description too ^^.

Personality:
He's an easy to handle and nice person while happy/comfortable.
He likes to laugh and can laugh about pretty much everything.
It's wearing him out to act "normal", which he does around people he doesn't know well enough yet. If he thinks that they would dislike/wouldn't accept what he is, they will never see his true face.
He tends to get angry when provoked while stressed, but if he is relaxed he laughs off every provocation.
He loves regular animals as well as fantastic beasts, and the tiny garden plants as well as the giants of the forests.
He is an absolute "foodie" and therefore likes to cook too.
He is incredibly passionate while cooking or crafting.
He likes to be on time.
It's hard to find something that really disgusts and quite impossible to find something that really scares him.

Home:
He has a big cave with one corner filled entirely with pillows. But he still has a hammock.
He also has a room with all sorts of tools, armor and weapons. Next to the room is a smithery which runs on magma.
There's even a tiny warm waterfall (his shower), heated by the smitherys lava, and a bit further up a big, cold, crystal clear lake.
If you go even further from there you reach a field of purple, blue and turquoise crystals and gemstones that glow strong yet softly. They are his main source of light in the cave.

Gear & Accessories:
His only accessoires is his earring, which is usually mostly hidden by his fur.
It functions as his housekey.
To use it he has to find a crack in a rock or rocky mountainside that's big enough to get through and then draw a secret sign infront of the cracks with the gemstone.
Then the crack will become an opening to his cave.

Abilities:
Morpheus possess magic powers that he summons with his thoughts. He can further increase their strength by chanting spells or making supporting movements.
He likes playing around with elemental magic (fire, ice, water, lightning, earth, etc.) as well as changing the very fabric of the universe (alteration [kinda] magic) and the mind (illusion [kinda] magic).
Interestingly his primary subject to work illusion spells on, is himself.
He also tries to get a hand on every "dark" or forbidden magic (like bloodmagic, curses, summonings etc.)...not for practicing them...just for the knowledge and maybe to use a curse as a blessing..
Even though he is a fine craftsman, his motorics tend to be a bit..raw. Making him (in close-quarter-weapon-combat) a fighter that relies on strength rather than flexibility and quick moves.
If he doesn't know the full strength of his opponent he prefers to summon close quarter creatures while backing them up with long distance spells.
His theoretically most dangerous move is "vanishing gate".
