Helwyr is waiting for us in the Southeastern area of The Heart.
To be able to go pay him a visit you need 80 magic and you need 40 kc or 20 if 50% reduction perk have been unlocked (4500 reputation with Seren Faction required).
The easiest ways to get there are using a Heart teleport (if you completed the miniquest "Tales of the God Wars") and teleporting to Nardah with a Desert amulet (2 or above) and running west from Nardah's bank.
Helwryr likes to bite and maul (he's kinda rabid), so it's better to use ranged or magic against him, but you can use melee too (I tried it and I survived
).Even though he uses only melee, he has several special attacks: he uses a couple of bleeds (run away from him before being hit, use anticipation/debilitate/devotion before being hit or reflect/resonance if you're using a shield and use freedom if you've been hit), he seeks stepmother Nature's help with a green gas released by poisonous mushrooms (surge or escape - the gas does 250 dmg per tick and it stuns you) and he also gets a little help from his alpha friends (you could ignore them but keep in mind they can mess up resonance).
The fight will follow this pattern: green gas - 3 autoattacks - bleed attack - 3 autoattacks - bleed attack (frenzy attack) - 3 autoattacks - alpha friends - rinse and repeat!
As soon as Helwyr spawns prepare to surge or escape because he could make mushrooms grow under your feet.
Pray against melee and if you have it use vampyrism aura.

It's hunting season! What?! Wolf is an endangered species?!
Not on Rs and anyway Helwyr is a known sheep killer!
