Capella

A glaistig fae, and a powerful witch.

Has magic of her own but mostly uses herbs and other reagents to create spell "bundles" for specific, powerful effects. She spends her mornings doing rituals while preparing these spells (did D&D Wizards do something like this in 4E? That's the only Edition I played and have a vague memory of).

The staff she carved herself out of birch wood, and is used as a conduit to direct spells.

When out in society she wears longer dresses to hide her hooves, and uses a minor glamor spell to camouflage her horns amongst a hat or other headwear.

Corbin

A shapeshifting forest spirit. His true form is that of a natural-looking raven, and his base shifting abilities allow him to transform into things that are approximately his own size (ferrets, housecats, etc, though always black with a bluish sheen).

With the enchanted birch twig that Capella gave him - and other more permanent rituals down the line - those powers are drastically amplified.

In addition to simply enlarging his whole body (giant raven form), he can grow birch branches over his body to create additional limbs. Any of his more defined forms can be mixed around to any degree (ie/ "harpy" form, just having wings in human form, etc.)

His human form is the most taxing to keep up, and he can't quite get it to 100%, hence the untransformable bird hand.

When the birch twig is active and growing into limbs, it simply grows at hyperspeed. When shrinking down or changing "skin" (to human form), the spell effects involve white "fire" and peeling birch bark.

Backstory

One day while out gathering in the woods, Capella was attacked by a gargoyle. She was caught off-guard and at a disadvantage, so she called for aid from the forest creatures, and the raven that had been watching her swooped in. She tossed him a heavily-enchanted birch twig that she carried in case of emergencies. Capella was only anticipating the twig to make the bird larger so she could escape on its back, but the twig reacted with the raven's natural magic and the wood sprouted, resulting in a giant, birch-legged bird-beast. Turns out he was a fully-sentient shapeshifter spirit.

They live in a cottage in the woods with a garden next to it and a stream nearby. The ocean is very close - the nearest town is a harbor town.
