Wandering Wagon

Description: The old Cambion Caravans Wagon that the party have been trawling around in since the first couple of sessions has seen a significant upgrade courtesy of Sir Hebron and the Unseelie Court.
Gone are the days of tired and worn wooden planks and fading paint, now the wagon is cast in a stylish purple wood with golden metallic trims. The previously relatively unguarded entrance to the Wagon proper has also had an upgrade with a set of wooden doors that can be locked (Details given below).
Perhaps the largest upgrade of all however can't be seen at all until activated. The Wagon itself has been granted a fragment of the power of the Sidhe and as such can grow a set of four Goat legs granting it extra movement, reducing the amount of terrain that counts as "Difficult Terrain", and increasing it's height.
The wagon itself has also been granted a limited amount of sentience in accordance with this, it doesn't seem too smart but is unwaveringly loyal (and rather stubborn).
All of this is unlocked with a very special key.
Statistics: The Wandering Wagon has two forms, standard wagon in which it looks like a regular (albeit snazzy and having a cannon on the front) wagon, and awakened wagon where it gains consciousness and grows four Goat legs.
First the Standard Form Statblock:
Type: Vehicle/Object Size: Large Creature Capacity: 8 Medium creatres Cargo Capacity: 800lbs Armour Class: 17 (15 whilst stationary) Hit Points: 200 (Damage Threshold 10, Mishap Threshold 20) Speed: 60ft (30ft per Rattelyr) Damage Immunities: Poison, Psychic Condition Immunities: Blinded, Charmed, Deafened, Frightened, Paralysed, Petrified, Poisoned, Stunned, Unconscious
Strength: 18 (+4) Dexterity: 10 (+0) Constitution: 18 (+4) Intelligence: 0 Wisdom: 0 Charisma: 0
Then the Awakened Form Statblock: Type: Construct Size: Huge (Extra size for Legs) Creature Capacity: 8 Medium Creatures Cargo Capacity: 800lbs Armour Class: 18 (16 whilst stationary) Hit Points: 200 (Damage Threshold 10) Speed: 100ft Damage Immunities: Poison Condition Immunities: Poisoned
Strength: 18 (+4) Dexterity: 14 (+2) Constitution: 18 (+4) Intelligence: 4 (-3) Wisdom: 6 (-2) Charisma: 8 (-1)
Actions: Kick Attack: +6 to hit, 5ft range, One target., On Hit: 2d10 Magical Bludgeoning damage and if target is Large or smaller must make a DC14 Strength Saving Throw or be pushed 20ft away from the Wagon.
Rules: Whilst in it's standard form the Wandering Wagon looks and acts like a normal wagon, to awaken it someone must take the Heartstone Key and place it in the slot located inside of the wagon's interior.
The person who did this is then temporarily bonded with the Wagon. Whilst in this state the person can command the wagon to do simple actions and it will obey (other people can give it orders it might not obey though).
Whilst bonded the individual and the wagon share a lifeforce, meaning that if either the wagon (whilst awakened) or the individual take damage the other will take the equivalent of the damage (the intended recipient will still take full damage, this is on top of that). This effect also applies to healing, so if one gets healed the other gets half the healing as well.
If the bonded person falls unconscious or dies the wagon will return to its standard form until someone bonds themselves with the vehicle.
If the Wandering Wagon gets more than 300ft away from the Heartstone Key then the key will transport itself back to the Wagons interior.

Mechanics & Inner Workings

It's all magic baby, mysterious Unseelie Sidhe magic.

Manufacturing process

Kill a smelly Halfling man who happens to be heir apparent to the Hollywrought line (or maybe some of the others). It worked the first time right?

History

A Boon granted to the party by Sir Balthari Hebron of the Unseelie court after the defeat of Ramul Hollywrought. Likely based on the famous walking houses of the Six great Halfling families in some way, maybe it's just what the Sidhe like?

Significance

A pretty hefty reward from the Unseelie.

Rarity

Artifact: This is a gift from the Unseelie Court of the Gloaming, replicating even a fraction of the Sidhe magic required to create this would be a lifetime achievement.
