Help Rood Raise a New Pet!
1) This quest, which starts with Pet Manager Rood on the central plaza in Heine, can theoretically be picked up at level 39. But since the target monsters have really nasty nukes I would strongly recommend that you wait until you are level 40 and can wear C-Grade jewelry.
2) Rood tells you about his plan to train young Lienriks, a kind of flying snake, as pets for the upper class.
For this purpose he needs Lienrik eggs. Agree to get them for him.
3) Lienriks (lvl 39, passive) and Lienrik Lads (lvl 40, aggressive) can be found in the Field of Silence, some way north of Heine. There are two subspecies of each, with different kinds of nukes: relatively harmless ice bolts and magic attacks from the normal Lienriks, nasty fire balls from the stronger Lienrik Lads and poison from the weaker Lienrik Lads. For the latter you will need Greater Antidote. And bring enough Healing Potions. Those flying snakes are all half HP, but there are a lot of them and they are all social with each other. You will get a blue, male egg from every other mob killed, and at a rate of about 1 out of 30 a reddish-pink, female egg. In both cases you get the same system message, so you may want to keep your quest notification screen open.
4) When you have some eggs, return to Rood. There is a complex payment system: for each blue egg you get 34a, for each pink egg 1025a. In addition to that you get a bonus of 2000a starting from the first blue egg and still one more bonus of 2000a starting from the first pink egg. So your best bet to optimize walking time/teleportation fees versus income is to return to Heine as soon as you have the first pink egg.
Here are some rewards I got:
And this happens if you ask Rood for your promised pet:
