Guild Wars 2

Hello I have just a few questions regarding the Sylvari.

1.)Are Sylvari glowing naturally and do they have control about it, does their “glow” depend on their mood? Are Sylvari glowing if they are blushing?

2)How does a Sylvari become a Warden, and how do they teach them. We know about Tegwen. She was mentored by Trahearne and became a Warden to guard Hamlet of Annwen. She later met Carys and began mentoring her. Is this the usual way of becoming a Warden?

Thanks
