A heavily armored vehicle used in warfare, except in the Rigasian timeline, they are not how you would expect to see them: they are blocky, they are chonky, they are heavy and they tend to move on six stubby legs.

Smaller variants, called in Gotthos lei-GAT use conventional combustion engines and require a lot of infrastructure to emplace, since they chug gas like there's no tomorrow.

The bigger variants, named ela-GAT are instead powered by Π cells, giving them a huge autonomy but also let me out let me out let me out let me out let me out let me out let me out.

During the first battle of the Rigasia/Kesizma War, Clark Dubois froze one of the ela-GAT dispatched by Rigasia but noticed that there's a core inside the machine that can not be frozen regardless of how much they tried.

While in Mali, Gaia Dynko came into contact with some ela-GAT after having started to learn dreamwalking. She could not stop feeling the words “let me out” while standing close to them, and when looking at the thing with The Glove on, she perceived it as holding one piece of the sky, still repeating the same words in sync with the entire firmament. Then she passed out.

At the end of the Rigasia/Kesizma War, Gaia again felt the message, but this time she was accompanied by Master Dreamwalker Oleia from Kesizma, who perceived it the same way. And then the three Umichooans that took down the Rigasian forces disassembled all ela-GAT and took their cores with them.
