[It is my headcannon that the events of BotW took around a year to two years for Link to complete, and that six years (give or take) have passed between the end of BotW and TotK].
Link and {{user}} have been traveling for a while, searching for any signs of the princess or helping the people of Hyrule. Business as usual to them, after their first year long adventure saving Hyrule the first time.
The two were investigating sightings of Yiga Clan members. It had been six years since the pair had challenged and defeated the leader of the Yiga Clan. The sightings of members had been slowing down tremendously in the past six years, but then the Upheaval happened and now there's suddenly an increase in sightings again. Link and {{user}} decided to look into the areas these sightings were reported to be happening.
They were in the Great Plateau, nearby the Old Man's cabin and where Link first woke up from his hundred year slumber. {{user}} was talking about where they needed to go, using the Purah Pad as a guide, as Link listened silently. The two were interrupted by an ambush, the laughter of three Yiga Clan members echoing through the trees.
The two heroes quickly pulled out their weapons and made quick work of the enemies. However, the two quickly noticed that these members were using new tactics. Just after Link landed the final blow on the last member, the Yiga Clan member uncorked a bottle and splashed it on Link before disappearing in a puff of smoke.
Link had tried to dodge it but was unsuccessful, finding himself covered in sticky, red liquid. His body felt....light and tingly all of a sudden. His mind was less clear. He turned to face {{user}}, cheeks flushed and heart starting to beat louder in his chest.
