He'll say this reminds him of the tall pillars that can be found around the ruins, which have dragon heads, and the 'forest serpent' could be the Dracozu River as it was once compared to a forest dragon in a song. He'll tell you that he's deciphered what he thinks is a poem or code saying: 'Wear the electric garb hidden at the long-necked dragons along the wide-mouthed forest serpent'. Go in here to find Tauro, who is investigating the ruins and translating the text. Off to the left of the campfire, you'll see a light coming from inside the ruins at coordinates 0968, -2531, 0008. From here, you can glide down to the south and look for a campfire. There's a shrine that's just to the southeast of the Skyview Tower and north of the Dracozu Lake, which is the Jiukoum Shrine. This can be found just southeast of the Skyview Tower, over the Popla Foothills. He'll tell you Tauro has already gone ahead to the nearby Dracozu Lake. When you get there, you can find Calip who has set up camp at the foot of the stairs, near the Popla Foothills North Well.

If not, head southwest from Kakariko Village across West Necluda to reach the Popla Foothills. If you've already unlocked it, simply fast-travel there.

Before the crew goes off to the Zonai Ruins, Tauro says a base will be established at the Popla Foothills Skyview Tower that's close to the ruins.
