Can she pass a DC 60 perception check to hear the rather loud noise of stone being magically shaped, from 200 ft away through several thick walls?

1d20 + 23 = 36.

No, she cannot.

Wait which one of us is Dergaix and which is Faumetun?

I Suggest each of you sit still and be quiet until the end.

The DC is 16, but it's a very reasonable suggestion, so they take a -1 penalty.

They both have +7 Will saves.
1d20 + 7 - 1 = 16.
1d20 + 7 - 1 = 22.

Dergaix fails, Faumetun succeeds.

We can only beat her Suggestions like half the time, and if we pass she'll just use it again and also be angry about it.

So I'm going to roleplay like it worked for now.

Anyway, you are currently in a mountain in southern Belkzen. Belkzen is full of orcs who are likely to see you as a challenge to grow their names, so you'll want to avoid them for now. It does have some nice warm nesting spots but that won't be your problem for a while.

In the north of Belkzen is the territory of another red dragon family. Avoid it. There are also powerful dragons in a few other places like in Five Kings and west of us in Varisia. You'll want to avoid them too. You shouldn't even be thinking about claiming any significant territory until you're at least 400.

No, I'm only 130.

You're both 3.

Anyway, if you fly straight east you'll reach Lastwall. That place is overrun with paladins and if they see you they'll kill you. The lands further south are likewise overrun with hordes of mortals. You especially don't want to go southeast, to Nidal. Far to the northeast the land is infested with demons, you won't want to go there, and if you go north in general it starts to get really cold which is quite unpleasant.

Now, as long as you're young you'll be pretty stealthy, and most things you come across will go down fast to your fire breath. That should be your number one strategy: Sneak up, burn, if burn doesn't work fly away and find something that does burn. You won't want to think about maybe having some wyrmlings of your own until you're at least a hundred.

If all you ever think about is survival though, you're basically feral, no better than the people you're eating. That's why it's important to have a hobby. Personally, I collect treasure. Somewhere there's a hidden entrance with another room behind it where I've stashed all the shiniest gems and coins I've found. It's not a huge amount but it's important to remember the little things in life that bring us joy, so everything I’ve found that looks valuable I've gathered there.

You can't have that hobby, obviously. It's my hobby. Pick a different hobby for yourselves.

Probably I should mention the most important thing. The most important thing about being a dragon is -

Can she pass a DC 35 perception check to hear several people running from 150 ft away, in an echoey cavern, through only one wall?

1d20 + 23 = 39.
Yes, she can.

Arkernux stops mid-sentence. They still sound far enough away for some personal buffs.

-“Oh no my treasure!”

She’ll leap into the air as she casts Haste (including the Wyrmlings in the effect because she can so why not), Invisibility, and-

No more time. His party rounds the corner into the chamber, only thirty feet away.

He flies near the ceiling, to avoid being attacked from above. The other six orcs and one wolf present hold together below him as they charge through the cave. 

Trahk Mul is a Barbarian (level 12), for those keeping track at home.
He is currently Enlarged, Hasted, Flying, Raging, Protected from Energy (fire), and has Heroism, and Bull’s Strength.
He wields a magic greataxe, now also Large.

His warband has a Sorcerer (8, Orc bloodline), two Clerics (8, Lamashtu; 6, Rovagug), a Ranger (8, with a wolf companion), and a few lesser barbarians who think Trahk Mul is pretty great and they should throw their lot in with him.

They are carrying with them a Tribal Standard, as any group of orcs obviously would be.

Excuse me, I am under a suggestion to sit still.

I'm not. Gonna rush out the back door now.

Have a nice dying brother.

The Rovagug cleric isn’t with their squad. He's only loosely affiliated, really.
He Stone Shaped the back door closed and charged in with some buddies of his.

Would you like to fight them?

Oh shit change of plans going back in.

Arkrernux sees the party.
Zarhbub, possessing 90 feet of darkvision and See Invisibility, spots her too.
The wolf, just barely within range of scent, smells her.

Initiative:
Zarhbub: 1d20 + 2 = 22.
Arkrernux: 1d20 + 4 = 20.
Wolf: 1d20 + 5 = 7.

She’s right there. Everybody attack over there.

No I’m not.

Bark!

Fine, maybe I’m over here.
Sense Motive?
