IBlizzard ipapashe inqwelwana esemthethweni kwenye yezisele zokuqala esiza kuba nethuba lokundwendwela eCataclysm: I-Stonecore. Le ndlu ise-Deepholm kwaye inyani kukuba iyonwabisa kakhulu.
Ndinethuba lokuyidlala amatyeli aliqela kwaye ngaphandle kwencukuthu, sisisele esimnandi sentolongo. Sisisele esinabaphathi aba-4 kwaye apho siza kubona umhlobo omdala (kuphela kwabo badlale kwi-Burning Crusade): iMana Storm Mill eyayitshixwe ngempazamo e-Arcatraz. Le Gnome ibonakala ngathi ijoyine inqanaba leTwilight's Hammer (asazi ngenene ukuba kutheni kunjalo).
Ndiyeka ukukunika i-ember kwaye ndikushiya kunye ne-advance esiyiziswa yiBlizzard. Ungayibona emva kokutsiba okanye kwifayile ye- iwebhusayithi esemthethweni.
Ngaphakathi kweNdlu yoMhlaba, nzulu ngaphakathi kwe-Deepholm, kukho iCore Core. Kwakukule ntsimi ingaqondakaliyo ukuba iTwilight's Hammer isebenze kwi-Deathwing, ifakela iipleyiti ze-elementium kulusu lwe-Aspect Dragon ukuze ibambe umzimba wayo othukileyo. Kulapha ke apho u-Deathwing waqala ukunyuka kwakhe esiya e-Azeroth, esaphula iNtsika yeHlabathi edumileyo kunye nokuzinzisa wonke ummandla wase-Deepholm.
Nangona i-Dragon Aspect eyonakeleyo ihambile, abalandeli bakhe bakaThilight's Hammer abathandekayo basazinzile kwezona ndawo zinzulu zeLitye Core. Kweli qela labanquli elinenzondelelo, ukunyuka kuka-Deathwing kungumhlaba ongcwele, kwaye bangakuvuyela ukuncama ubomi babo ukukhusela ubungcwele bakhe.
Kutshanje, amaShaman eRingi yomdongwe afikile eDeepholm ukulungisa iNtsika yeHlabathi eyophukileyo. Kodwa iinzame zabo ziye zahlaselwa liqela lemikhosi eyoyikisayo, ngakumbi iTwilight's Hammer. Njengamaqhawe e-Horde kunye ne-Alliance alwela ukunceda i-shaman,
I-Stone Core iye yaba luphawu olwehlisayo kulawulo olumnyama
abalandeli baka-Deathwing basenayo kwi-Deepholm.
Ngaphandle kobukho beetempile zeTwilight's Hammer, iinkcukacha malunga neLitye Core azikho. Abaphandi abambalwa abaye bangena kwindawo engcwele yangaphakathi yeTempile yoMhlaba bathetha ngeendlela ezibukhali, ezingalunganga, umsebenzi wezilwanyana eziseza kufunyanwa, ezihamba kuloo mmandla, kwaye zihlala zikhokelela kukuvalwa. Eyona nto iphazamisayo ziingxelo zelitye elikhulu le-wyrm elalizimele phantsi kwezithunzi zommandla ongaphantsi komhlaba. Ngaphandle koko, nantoni na ekhusela ukunyuka kuka-Deathwing kwimiqolomba enzulu ye-Stone Core iyimfihlakalo.
Akukaziwa ukuba izidalwa ezizalwe kwi-Stonecore ziphantsi kolawulo lwe-Twilight's Hammer. Nangona kunjalo, akukho mathandabuzo, baya kujonga abangeneleli ngenzondelelo. Ngaphandle kokuba laire yangaphantsi icinyiwe, iinzame zeNdawo yoMhlaba kunye neminye imikhosi elungileyo e-Deepholm iya kuba lilize. Logama iTwilight's Hammer igcina ukubambelela kwayo kwiTempile yoMhlaba, wonke loo mmandla uya kuhlala ugqunywe kwisithunzi esihlala sihleli se-Deathwing.
