Runescapee

The crashed meteor you spotted is a shooting star.

From what I understand, you have to use a telescope in someone's house to determine where it will land or go the observatory, south of Ardougne. When you know where a shooting star is going to land, you can head there and try to mine your way through the outer layers to free the star sprite and get your reward. If you are the first person to attempt to mine it, you will be rewarded with a hefty chunk of Mining experience (there is no Mining level requirement to claim this bonus).

Shooting stars come in a variety of sizes, and the larger they are the harder the outer layers will be. An exceptionally large star can have as many as nine layers, while very small stars will only have one or two. Because of the remarkable hardness of a large star, only the most experienced miners will be able to penetrate its shell until the more brittle layers are exposed. You can find out how large and hard a star is by prospecting it.

Star sprites, being magical creatures, are capable of using the stardust you gather from their homes to create objects and items, and are more than happy to do so. To claim your reward, simply chat to the star sprite while it stands around in the remains of its star. Note that you can only claim a reward once per day, so you might like to hold onto your stardust until you have some more (up to the maximum of 200). But you only get a reward for once per day.

Oh you'll grow bored of the content in 1 month.

What you were talking about is the new D&D as explained by the above posters, their only purpose is free exp that's about it.

If you talk high level content, there barely have been any updates, I only recall "While Guthix Sleeps" a quest that opens up a new monster, Tormented Demons, which can attack in three styles, with a special combo attack that hits twice. Very dangerous, but you get the new "super dragon dagger" the Dragon Claws from them. Goes for 27m~ in GE.

There's also a new Pest Control style combat minigame. What do I mean? I mean free combat exp. So the Soul Wars products are shunned upon Pest Control products who are shunned by RS2 Products who are shunned by RSC players.

Of course theres the new over 9000 mid-level quests that nobody really gives a **** about, you can now Pray-X at the POH altars, I can't recall anything else other than that.

Oh yea there was a glitch in the PVP worlds but was fixed recently, but since you don't care I won't elaborate.
