Hanaq

The scale of Hanaq's islands are surprisingly intimate. Most planets (sometimes called planetoids) have a surface area comparable to a small region that could be crossed by foot in a few days. Even Hejmen, the largest known planet, could be circled on hoof within a month.

The world is more akin to a magical archipelago than a vast cosmic expanse, where wooden ships regularly travel between worlds and floating islands are common habitable spaces.

Sunflowers are burning blooms atop stems that spring from Hanaq's barkstream, providing light and heat to their surrounding planets. While planets vary in size, they are typically sizable enough to support stable floating islands and airship travel.

Distances between Sunflowers vary, with travel times ranging from three to fourteen days using typical airships. Most planets maintain a 24-hour day/night cycle through their rotation, though exceptions exist, such as Nimbudai with its extremely slow nights.

Planets and Sunflowers connect to the Barkstream through massive structures called Twigstalks. These mile-wide connections feature twin rotating currents of water arranged in a double helix pattern, with calmer waters between the spirals. The planet or Sunflower typically rotates around this axis, with the connection point marked by a perpetual suspended geyser.

Skilled helmsmen can navigate these currents to quickly descend to the Barkstream in a minute, though the risk of spinning out makes this dangerous for inexperienced pilots. While the gentler waters near the bark make it possible to touch Hanaq's surface in these areas, swimming too deep into Twigstalks is extremely dangerous and strongly discouraged.

Most Twigstalks rise to, at most, the height of a skyscraper, making them prominent navigational landmarks. The specific current patterns of each Twigstalk are carefully documented by pilots, as successful navigation is greatly helped by intimate knowledge of these local conditions.

Hanaq has four major branches, known as the Four Systems, which extend outward from the trunk. Currently, two branches have been explored in the story, each housing a number of planetoids.

Hejmen, the largest known planet, serves as a central hub for much of Hanaq's civilization. It sits at the crown of Hanaq, the part that stands in between the upper branches and the trunk.

The trunk is the bottom half of Hanaq. This expansive region is yet to be seen but is known to house the powerful empire of Warden, Esperanto's largest rival. What is known about the trunk that there is a distinction between the outside of the trunk the and the inside.
