The tents remind me of Lyn from fire emblem on the GBA

The similarity is not a coincidence: both Dias’ feud and the Sacae region of Fire Emblem were clearly modelled after the steppes in Inner Asia, where nomadic peoples use this sort of tent (known as “yurt”, “ger”, and by other names; it depends on the language) fairly often.

The main appeal of this sort of tent is that it’s large enough to be a home (unlike a camping tent) but can be reassembled relatively fast, if you want to pack and leave and stay elsewhere. A competent group can assemble it in a single hour, as in the video; but you could do it even on your own if necessary/desired, it’s just that it’d take longer.
