Melchia approaches the boy, gazing at him as if looking at him for the first time, as if he is only now acknowledging his presence as a living thing. Kneeling down to his level, he speaks softly to him, staring directly into his eyes.
"Relax, Zadsa. You are safe now. Do you mind if I ask you some questions?"
The question was a formality, however. Silently, subtly, he tried to alter the boy's disposition towards himself, using his will alone.

Melchia will manifest Attraction on Zadsa, expending his psionic focus to boost the save DC. Zadsa is entitled to a DC 15 Will save. On a failure, he will become attracted to Melchia, making him interested in, and wanting to be near, Melchia. Melchia will gain a +4 bonus on social interaction skill checks with the boy. All of this will last for 1 hour.
On a success, nothing happens.
Melchia will make a Concentration check to try and manifest the power without its display, DC 16: (1d20+6)[26]
This is a telepathy Charm effect, so the elf racial bonus on saving throws might apply.
