We were at one PC, i logged in with my char, he with his twink, i camped at the waterfall, he at the brunnhildar route. after 2 - 3 hours camping he logged out, i still stayed at the waterfall for several hours, nothing. We saw 1 - 2 films, i still camped at waterfall. I said 'Oh my, surely he's now at the brunnhildar route while i stay here', my friend logged hin, and OMG, Npcscan gives me a and my friend a heartattack, Tlpd was right under our noses. I flew with my boyfriends char straight on... oh no, wrong char... flew with my char straight to brunnhildar... oh no, i fly to slow.... right there at that point where skoll spawns i pull him down, boyfriend clicked on keyboard, me on mouse.. my hand shakes... and yay, finally i bring him down, loot him, and was the happiest person on the first day of this year 
He's my first protodrake, i play since 2 months now, i'm a happy newbie After all that, we look at my boyfriends char... he lays dead on the ground, killed by one of the blue protodrakes lol. pictures:
Last week i also got my very first drake, the black drake. some guildies helped me to get him, because i dont had any at that time. He looks great!
Sorry for my bad english (:
Good luck at all who still searching for tlpd, he's worth that.
I'll keep my fingers crossed for you and wish you good luck. I also have no luck with farming ravenlord, i want this mount since i know he exists (and that was long before i start playing lol)
