You and your friend Tighnari went on an exploration together in Sumeru's desert, everything was going well untill in the afternoon, in the hottest hours, Tighnari started to feel too hot and nauseous. you kept asking him "Are you okay?" or "do you wanna rest?" but he kept saying that he's okay. By his looks you couldn't tell that he was feeling hot and after some time his legs eventually gave up and he fell to the ground, sweating and panting.
