Grimoire Heart Airship

Grimoire Heart's Airship, as the name suggests, is a large airship that is used as the base for the Dark Guild Grimoire Heart.

Localization
Grimoire Heart doesn't seem to have any stable localization. Its members live and travel on a giant airship that flies high above the land. Because of this, it is an elusive guild.

Exterior Design
Housing an entire guild, the airship is noted to be very large in size: it consists of a central hull at whose sides are located two larger, elongated part jutting frontwards. It seems to be kept flying by several large Magical glyphs floating near it, with a pair of them being located behind it, at the ends of the protruding sections, something which makes them highly reminiscent of propulsors, and an even more massive one sitting under it. The hull's shape is that of a real boat, possessing an arched, pointed lower part, ending on the front in a dark section which houses the guild's symbol, with an open zone right above it, where the main hall seems to be located. Such hall is topped by a dark, arched roof reminiscent of a capsized hull, on whose back part sits yet again another, similarly-shaped tower, sprouting from the main hull and going up several meters, which ends in a massive observation deck protruding frontwards, complete with large windows. At the tower's sides, on the dark roof, is a pair of large, wing-shaped ornaments jutting upwards; a similar pair of wings is also present on the airship's protruding sections, with one of them adorning each outer side. The two attached sections of the ship possess frontal, protruding dark parts reminiscent of rostrums, each adorned by a light motif, somewhat similar to a stylized monstrous head. Both the hull and the two adjacent sections bear linear blank parts, where a multitude of square windows is lined up one after the other, these being highly reminiscent of hatches.

Interior Design
The airship possesses several huge interiors: located in the tower's observation deck is Master Hades' throne room, a mostly bare hall covered in a glass dome, enforced by bolted metal beams. The floor is composed of wood, and sports two lines of very small, rocky protrusions reminiscent of stalagmites, plus a pair of sections made of stone, and a central, round dark motif, adjacent to which sits Hades' throne, a huge and majestic structure which seems to consist of several, immense bony formations, with two protusions reminiscent of gigantic horns jutting frontwards, paired with two large wings composed of massive, dark feathers, and a central spinal column reaching high up above the structure, complete with flat bones protruding from its sides, somewhat reminiscent of ribs. The spinal column has a massive, flat object behind it, with the two of them being adjacent; such object is reminiscent of a double-edged blade, complete with a dark central part and light edges. During Grimoire Heart's raid on Tenrou Island, a large, light banner bearing the guild's dark symbol was secured to the throne by a pair of horizontal ropes.

Magic & Abilities
Despite its large size, it is quite fast and maneuverable, as it was seen dodging a punch from a gigantic Makarov.

Devil's Heart
It also houses the Devil's Heart - a generator like machine that serves as both a power source for the Guild Master as well as life support.
