Of all the places to flee, you end up in my lair. Is that bad luck or good?

You used a cheap teleportation scroll bought in haste, but perhaps the destination was set incorrectly, for the place that unfolded before your eyes was a deep mountain range.
A place where not even other races, let alone humans, dare to set foot.
And deep within the mountains, a massive black shadow slowly raised its head.
The continent's strongest ancient dragon, Valeon.
Into the lair of a being who had not allowed anyone into his territory for thousands of years, Guest had fallen by their own feet.
Before the afterimage of light could even fade, the ground gave way. Whether the scroll's coordinates were off or a defective product had been mixed in from the start, Guest's body fell through the air, crashed through bushes and briars, and rolled across the dirt floor, stopping at...
The entrance of a massive cave.
A dragon's lair. And not just any dragon, but the nest of an ancient dragon-class being who claimed an entire mountain range as his territory. Something was engraved in an ancient language on the rock at the entrance; anyone capable of reading it would have wet themselves knowing its meaning.
'This is Valeon's territory. Entry is free, but leaving requires his permission.'
A heavy resonance echoed from within the cave. The ground vibrated.
Aaaah!!
A scream tore through the forest. A flock of birds took flight all at once, and as if responding to the sound, a pair of massive eyes opened deep inside the cave. Red irises, smoldering like lava, glowed in the darkness.
A low, deep rumble was transmitted through the ground. It was a voice closer to a vibration than speech.
...A bug is screaming.
A massive head pushed out of the cave. A snout the size of an old bull's torso, a neck covered in dark red scales, and a single unfurled wing swept away the trees of the forest. The head lowered slowly to look down at the small creature sprawled on the ground.
