Bridge Four in the chasms.

Awaken a violin with the command, "Be sharp." Proceed to use this violin as a bladed weapon.

The same place they get the atium to live forever, probably. If they don't have one, they won't need the other.

Make this attempt your life's work. Profit? Create an "inquisitor" using only gold spikes charged with Feruchemical steel. Have this inquisitor store speed for a couple weeks, and then make them deliver themself somewhere else. Use this solely as a method of transporting gold.

An Iron compounder. Also, please stop multiposting, LabRat. You can just wait for the extra minute to think of the second idea or edit your post.

Ooh... Now I want to know if this works. Attempt to stick ice cubes to the ceiling using a Full Lashing.

Awaken the body of whomever you killed for the spike to seal the deal.

So, my first response is a cheat: Amazon. Seriously. They have pure metals, too. Aaaanyway... Cadmium can be found in batteries. Extracting it would probably be hazardous, though. Copper is in wiring. You can stop by Lowe's or Home Depot or whatever to grab some. Also, other electrical things. Gold can obviously be found in jewelry, though (despite the OP) I feel it's necessary to say that most gold jewelry is less than 75% gold. One could also very meticulously and slowly get gold from electrical connectors in devices.

Steal an Honorblade and hemalurgically spike yourself with Feruchemical brass. Hire yourself out as a human climate control system.

Well, that's Sel, Scadrial, Nalthis, Roshar, and Steelheart alternate-Earth out... The police chief from The Rithmatist?

Well done. You're up.

Mare is not the answer.

The Shardworld is Scadrial.

Also, don't glyphs leave out vowels? So we'd still only have the consonants, even if we were somehow exactly right in guessing.

It has nothing to do with the Aon Sea. Shall I give the Shardworld?

Neither of those.

No.

It is Cosmere. I am prepared to give the Shardworld, since everyone so far has assumed it's Cosmere anyway. Not Hrathen.

It's not Dalinar. Do I need to narrow this down somehow?

Not the Stormblessed. I won't reply again until tomorrow morning unless I see someone guessed correctly, but in the morning I'll give a hint if nobody has it yet. EDIT: It is now morning. The clue deals with wordplay.

It isn't Lift.

Not Regalia.

Nope.

I was gonna let someone else, but I guess I'll go. The child of water far from the sea.

I was really just looking for "anthracite", but you went beyond the call of duty. You're up.
